Hello there. I had this machine running for quite some time: FreeBSD 2.2.2-RELEASE #0: Thu Nov 6 07:55:43 CST 1997 And this morning I had a crash. It looks like problems in the scsi bus, and I would guess some hardware going bad. I am including the /kernel messages as well as the boot dmesg scsi related output; So, how do I track the problem and correct it ? Thanks, ================================================== Raul Zighelboim mango@staff.communique.net [Raul Zighelboim] ========/var/log/messages Jan 27 01:12:16 kiyoko /kernel: sd1(ahc0:0:0): Target Busy > Jan 27 01:12:17 kiyoko /kernel: sd1(ahc0:0:0): data overrun of > 16777215 bytes detected in Data-Out phase.
